Description

Technical area

[0001] The present invention relates to a magnetic connection system according to the preamble of patent claim 1. State of the art

[0002] Previously, the magnets (outer and center magnets) and poles were connected using a soldering process. This has the disadvantage that the magnets with different magnetic orientations must be magnetized before the soldering process. This, in turn, has the disadvantage that geometric inaccuracies would require post-processing, which always causes problems in the magnetic state. Description of the invention

[0003] The present invention is based on the object of eliminating the aforementioned problems.

[0004] According to the invention, the above object is achieved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments and further developments of the magnetic connection system according to the invention are specified in the dependent subclaims.

[0005] The solution to this problem would be a positive and force-locking connection between the outer and center magnets. The outer magnets are always attracted to the center magnet by the special geometric step formation. The step formation can be attached as often as required and arranged in any desired position. The clamping force is applied to the outer magnets by means of the holder's clamping claw. By clamping the clamping claw, the outer magnets are pressed vertically downwards, while the center magnet is held in position by the holder. The positive and force-locking connection as well as the precise positioning of the center magnet to the outer magnets is thus created by the key element "special step formation". The shape of the step formation and its arrangement influence the attractive force between the outer and center or inner magnet.

[0006] The locking part locks the connection between the outer and center magnets. In its simplest form (Form 1), the locking part prevents the outer and center magnets from shifting vertically relative to each other. The locking part provides redundant protection in the event of a mechanical failure of the "special shoulder design" and also offers the ability to absorb repulsive magnetic forces. The latter allows the connection of magnets magnetized in the same direction.

[0007] With additional special geometry variants (Form 2) of the locking part, vertical displacement of the components relative to each other and simultaneous permanent attraction between the outer and center magnets can be achieved. This enables use at low temperatures.

[0008] The locking part can be designed so that it can be inserted or removed with minimal force. Additionally, after the locking part has been inserted, it can be deformed (elastically and plastically) with a tool so that the play between the locking part and the connected parts is eliminated. Depending on the deformation of the locking part, an elastic preload can be created between the components.

[0009] The possibility of plastically deforming the closure part with a tool also opens up the possibility of the closure part being inserted as a simple component (Form 1) into the recess of the outer and central magnet and then being plastically deformed in such a way that the closure part takes on Form 2 (one of the variants) after the deformation process.

[0010] The special geometry (special shoulder design), which creates the positive and frictional connection between the outer and center magnets, can be installed either individually or in multiple locations. The same applies to the locking part.

[0011] The number of components that are connected using the new connection method is not limited to the outer and center magnets listed in the example and can be expanded as needed.

[0012] In this application, the pole assembly and magnet pack (consisting of outer and center magnets) can be used as a support when mounting the pole assembly into the holder. This means that the magnet pack can be pre-loaded onto the pole assembly and then installed together in the holder. The assembly can also be installed individually into the holder.

[0013] The pole connection is specified as a soldered connection in this application, but could be connected together using the same principle.

[0014] The special geometry could also be designed to prevent axial displacement of the components relative to each other. In this example, this is not necessary, as the pole assembly prevents axial displacement.

[0015] The magnet and pole assembly can be clamped using the holder and its integrated clamping jaw. The clamping jaw geometry can also be designed with a defined plastic zone to compensate for manufacturing tolerances. The clamping jaw can also be designed as a separate component.
